Browser Cache FAQs

Should I clear cache in Firefox?

Like Edge, Safari, and Google Chrome, browser cache in Firefox is used to store website data, including your login details. It allows you to access a previously visited website with less loading delay. That makes cache important for people who need quick access to sites without having to load the page every time or remember their login credentials.

However, clearing your cache could solve the issue if you’re experiencing problems in Firefox, such as trouble loading a webpage or seeing a video. But before you clear your cache, it’s important to know what happens, so please continue reading to learn more.

Does clearing browser cache delete anything important?

If you save your login credentials in Firefox, then clearing the cache will remove those credentials. That means you will have to re-enter your usernames and passwords for your saved sites. And if re-entering your login credentials is a problem for you, then clearing your browser cache does delete important information.

Fortunately, you can select which cache to delete in Firefox, meaning you can remove website data without removing your login credentials. The How do I clear my cache in Firefox section provides a detailed guide on how to do that.

You can also clear history for a specific time range, although doing so will not affect cached web data.

What happens if I clear my browser’s cache?

There are different types of cached data that you can clear in Firefox: Cookies and Site Data, Cached Web Content, and Browsing History. The list below defines what each option will remove.

Removable cache in Firefox:

• Cookies and Site Data
  • Clearing cookies and site data may sign you out of websites you’ve signed into.

• Cached Web Content
  • Clearing web content means you will have to reload websites you’ve previously visited.

• Browsing History
  • Clearing your browser history means you won’t see the websites you’ve previously visited.
